What a difference this affair shows regarding the Air Safety culture in Europe re some other parts of the world.
AirAsia have had the CVR and FDR info for a month or two now, and yet not a word of a preliminary report of the fatal A320 accident off Indonesia, again seemingly crew related.
I would guess that the distinct nature of the accidents force that approach. Once it became evident that the GermanWings crash was intentional, the kind of inquires going on would be different, so it would eventually leak to the press. Better control the information flow turning it public ASAP.
